AUTOMATIC WEIGHT AND COST SCALE.

' Application filed June 23, 1906. Serial No. 322,985,

. To all whom it may concern;

Be it known that I, MAGNUS 'UNGER', a naturalized citizen of'theUnited States, and resident of Schenectady, in the county of Schenectady and State of New York, have invented certain new and useful Improvements in Automatic Weight and Cost Scales, of which the following is a specification.

This invention relates to an automatic scale, which is designed to perform the double function of indicating the weight and the price of the article placed thereon.

It consists essentially of two relatively movable indicators mounted'upon a suitable frame, and adapted to indicate the weight and costupon-suitable-dials. The movement of said indicators is automatically controlled and the proportionate amount of relative movement predetermined by suitable and adjustable means. The weight of the goods causes said relative movement, which is therefore directly proportional thereto.

The details of construction of one embodiment of my invention are represented in'the accompanying drawings.

Like parts in the-several views are indicated by like figuresof reference.

Figure 1 is a front elevation showing the indicating dials. Fig. 2 is a side elevation,

with the casing removed to show the internal construction. Fig. 3 is a cross sectional view taken inthe plane indicated by the line 3-3 of Fig. 2.

In the embodiment of my invention as represented in the drawings, 1 represents a standard or frame upon which is mounted in suitable bearings a rotatable shaft 2, to which may be attached, at one extremity, a suitable pulley 3, adapted to. receive circumferentially and be rotated by a flexible supporting member 4. Said supporting member 4-may be attached at one extremity to a suitable scale-pan 5, in operative connection with a tension wei ht spring 6 attached to said standard or" frame 1. Said rotating member 2 may be provided with suitable spring 7 which is adapted to resist the rotatlon of said member 2 caused by the'weight upon thescale pan 5 and return the same to its zero position when the weight is removed from the pan 5. s

'A friction disk 9.may be positioned at the inner extremity of the shaft 2 andheld by means of a spring 8 in contact with a suitable friction wheel 10 which when in its normal or zero position is out of contact with the friction disk 9, by reason of a radial slot or recess 9 which is provided in said disk at this point. The sliding movement of the friction disk 9 caused by the spring 8 may be limited by a suitable collar on the shaft 2 to an amount sufficient to cause a small pressure between the disk 9 and the friction Wheel 10 and rotate the latter when the disk is turned by the pulley 3, as described. The friction-wheel 10 may be splinedor slidably mounted upon a shaft 11 journaled in said standard or frame 1. As illustrated in the drawings a key 27 is attached to the shaft 11, which key is of sufiicient length to permit the sliding of the friction wheel 10 upon the shaft 11 to obtain the desired adjustment and resultant relative movement. between the members. In the embodiment of my invention as herein represented, I have provided as means for adjusting the position of said friction wheel 10 upon said 'sha-ft l l, a suitable support 12 attached to a reciprocating member 13, whichmay, also be journaled in said standard or frame 1. The support- 12 may also form a bearing in which the wheel 10 is rotated. Said reciprocating member 13 may be adjusted and held in position by a lever 14 provided with a handle 18 adapted to be tightened against said casing 15 when the lever 14 shall have been placed in the desired position. An index 19 may be provided to register the position of the niembersupon a suitable dial 20 in'terms of unit price, or other desired terms. Said shaft 11 is in operative connection with a rotating shaft 21 journaled in said frame or standard 1. Said shaft 21 may be'provided with a torsion spring 22 to resist the rotation thereof and also to returnthe same and the indicator 24 to its zero position when the weight indicator 23 is in its zero position and the slot 9 in the disk 9 standing opposite the friction wheel 10, which at this point is out of engagement therewith and conse quently free to be rotated, as described. Suitable indicators or pointers 23 and 24 may be provided at the outer end-oftheir respective shafts to indicate the amount of rotation thereof upon suitable dials 25 and 26 in-terms of weight and cost, respectively, orany other desired units.

' In the operation of the above embodiment of my invention, the article of weight being placed upon the scale pan 5, the shaft 2 is rotated by the pulley 3 and flexible support 4, the weight thereof being indicated on the scale 25 by the indicator 23. The friction wheel 10 being brought into contact with the disk 9 by the rotation thereof is in turn rotated to a greater or less degree according as it is positioned at a greater or less distance from the center of said disk 9. To place said friction wheel 10 in the desired position, the lever 14 is moved up or down according as it is desired to adjust the wheel 10 at a less or greater distance from the center of the disk 9. A support 12 is adapted to carry and slide the friction wheel 10 upon its shaft 11. Said support is attached to a sliding member 13 which is moved up or down by the lever 14 which may be pivotally attached at one end to the casing 15 and provided with a slot 16 adapted to receive a pin 17 attached to said sliding member 13. A threaded handle 18 may be provided which is adapted to be tightened against the casing 15 and hold the parts in the desired position.

An index 19 may be provided at the upper end of the sliding member 13 to indicate the position in which the parts are adjusted in any desired terms upon a suitablescale 20.

The scale 20, being correctly calibrated at the price per pound, or other .unitof measure desired, the dial 25 calibrated. to indicate the weight of the article on the scale-pan and the dial 26 calibrated to indicate the total cost, respectively, it will be seen that it is only necessary to set the index 19 at the unit price on scale 20 and the weight of an article placed inthe scale pan 5 will be indicated upon the dial 25 and the total cost thereof upon the dial 26 automatically by the relative movement of the indicators 23 and 24.

As m ny changes could be made in the above construction and many apparently widely different embodiments of my invention designed without departing from the scope thereof, I intend that all matter contained in the above description or shown in the accompanying drawings shallbe interpretedas illustrative merely of an operative embodiment of my invention and not in a limiting sense.
